The coconut palm (Cocos nucifera Linn) is undoubtedly the most economically important species in the palm family of Areacacea. Coconut meal is solely prepared from the coconut seed which, has been found to be attacked by several disease causing microorganisms especially Ceratocysis paradoxa, a fungus that causes the devastating Bole rot disease. The study is designed to assess the storage stability of coconut seed by applying bioorganic extracts of Mangifera indica on the bole rot pathogen, Ceratocysis paradoxa. Four different concentrations (3, 6, 9 and 12 %) of the stem and root extracts of M. indica were obtained using a fair-fold sterile cheese cloth and tested on the fungus cultured on plates of Sabouraud Dextrose Agar (SDA) medium. Data obtained was analysed using the two-way Analysis of Variance (ANOVA). The result showed significant fungal mycelial growth inhibition with the 9% root extract concentration than the stem extracts concentrations. The antifungal properties of M. indica root extract can be further harnessed, processed and packaged as one of the natural bioorganic alternatives to chemical fungicides.
